IMPROVED METHOD OF PREPARING PHAT AND OTHER SUBSTANCES FORXEUEL.

LOUIS s. ROBBINS, or NEW YORK, N. Y. Letters Patent No. ,6 0,24 8,: iated December 4, 1866., l

I sPE rFIoA'I'IoN. TO, ALL WHOM IT MAY GONOERNL i 3 7 Be it linown that I, LOUIS S. Romans, of; the city,county, and State of New :Yorkhavc iuventcda newh I and improved Method of Preparing Peat, Goal-Dust, and other Substances forFuejli and I dojhereby declarethat ,1

the following is a full, clear, and exact description thereof, which will enable others skilled inthc art toifully My invention consists in drying and -proparing peat, coal-dust, and other substances, ,cither separately or I in combination, so that the materialempioyed shall be economically and uniformly mixed and combincdduring the process of drying, and at the samc'tim efurnishing to the material employed, highly concentratedfand;

adhesive substances. It is well known that efi'orts have ben made from time to time to mix and combine coal,

tar, and. similar substances, with peat and coal-dust by mechanical. means, but the nature of peat is such that.

all efforts to do this with any degree of uniformity or economy have hitherto failed. After many experiments I have ascertained that thesubtle nature of hot oleaginous vapors, obtained from coal, tarpbitumemrosin, &e., will when properly applied permeate and saturate large quantities or bodies 'of those substances in a most th erough, uniform, and economical manner; 7 I will now proceed to describe my process.

I place the, peat, coal-dust, or other substances, either separately or in combination, in arccciveriofilaiiyw suitable size and form, and connect the. receiver with a still or retort containing coal-tar,avood tar,- bitunifejn, rosin, or any other oleaginous substance or compounds;- I then raise the heat, in thestill or retort sufficiently; high to cause the vapors to rise from the contents, and pass through and permeate evcry p ortionof the peat, coal-dust, or other substance contained in the receiver. The heat of thejapdrwill at first cxpclany moisture contained in the peat or other substance, The wateror' watery vapor will pass through a pipc attached'to the i receiver for the purpose; the outerfend of' the pipe will be submergedin water for the purposc of condensing, any of the oleaginous vapor which might escape with the moisture. The heat is continued until theconten tsbf" the receiver are suflicientlysaturated withjthe vapor, and are in a suitable condition to be moulded ior prcssed into blocks. When operating with coal-dust, the heat of the vapor is sufiicicnt to soften: it to such adegi'ee,

that when pressed the blocks are quite solid and retain their form while being consumed' in the life. I The vapors oduced from coal, tar, bitumen, rosin, and substances of like nature, on cooling, become very adhesiveandl reiiider the material when pressed into blocks'solid and tenacious, and the condensed vapor; beinguniformly distributed through the mass,th'e fuel ishighly combustible and concentrated,;a n d greatly superiorlto ahyifuel 9 hitherto produced from similar substances. When peat or other substances are prepared'fordomestic use, and,

consumers do not require a concentrated fiieh saturated with bituminous substances, and when it is only necessary that the material should be dried and pressed, I fill my retort with piecesof broken marble or anydsimilar, material, which will present an extended hcatingsurface; I then raise the temperature inthe, retort; to any required degree, (a red heat if necessary and force a current of air through it, and iiito and through the material to be dried, (peat or other substance,) by a bellows or in some other manner; which readily expelsihen moisture. I do not limit myself to any particular kind or form of: apparatus, as I am aware that there are many, ways by which the operation can 'be performed. Nor do I confine myself to thcmethods herein described of expelling the moisture by the use of the hot vapors or by heated air.

But having thus described my invention, what I do claim as new, and desire to secure byLettcrs Patent, is-

Saturn-ting peat, coal-dust, or other substances, either separately or in combiuation with hot olcaginous vapors, substantially as herein described.

I also claim the drying and saturating the peat, coal-dust, or other substanccs, cither binatiomat one and the same' operation,substantially as described. I

I also claim the method herein. described-of drying the peat, coal-dust, or other substances, by the use of .heated air, substantially as herein described.

The above specification of 'my invention signed by me this 13th day of October, 1866.1
